The new door fits in the frame but #1 is very tight side to side and figure if I could shave 1/8" off the latch side it would be enough to open and close properly and #2 the metal door is thicker by about 1/4" than the old hollow core door and if I could shave 1/4" off the stop part of the frame it would fit fine and be able to have some weather stripping. I'm just not sure how to make these adjustments (cuts) and still have it look decent. I do not want to replace or remove the frame itself since this one has the inset for the exterior storm door and being an older (50's) home don't want to disturb anything possibly hazardous. Looking for suggestions. I have circular saws and a router but corners would be an issue.
